Wonderful little nonogram game with cute art and characters!
I'd love to see more like this. If you do though, please include options for turning off autocomplete and especially turning off the greying-out of clues.
The way it is currently a clue will be greyed-out if its corresponding block is filled BUT there are times when this actually gives away the answer because the solution is still ambiguous but the clue tells you which block of cells corresponds to which clue, if that makes sense.
I think these features were added to be "conveniences" but part of the joy of picross is taking the time to fill in all the squares yourself and working out what options there are, so these actually take away some of the fun, I'm sad to say.
That being said, I loved the game overall!
